Environmental Detection of Parasites in the Marginalized Paiute Reservations Compared to a Nearby Area

Am J Trop Med Hyg. 2024 Feb 13:tpmd230712. doi: 10.4269/ajtmh.23-0712. Online ahead of print.ABSTRACTThe amounts of parasite DNA in soil samples from different playgrounds and other public areas can help identify areas of possible microbe transmission and give indications of the possible occurrence of parasite infection in nearby communities. We collected 207 soil samples from parks in Paiute indigenous tribal areas in southwestern Utah and from the higher income city of St. George, Utah, and tested them for 11 parasites that can cause human disease. Molecular tests revealed an elevated odds ratio (OR) of 3.072 (range, 1.114-8.065) for detecting the helminth Trichuris trichiura and an elevated OR of 3.036 (range, 1.101-7.966) for any protozoa (not including Acanthamoeba) in the tribal land playgrounds compared with St. George parks. These findings support previous studies showing that areas in lower socioeconomic communities, especially marginalized communities, tend to have more parasites in the soil, which may lead to higher disease prevalence rates.PMID:38350146 | DOI:10.4269/ajtmh.23-0712
